SAFETY PRECAUTIONS REMEMBER: "SAFETY" IS ONLY A WORD UNTIL IT IS PUT INTO PRACTICE Improper handling of the tractor could lead to an accident. Prior to the operation of the tractor, be sure to read this Manual carefully and have a thorough understanding of all of the contents. In particu lar, the instructions given in this section entitled "Safety Precautions" must be strictly followed. 2. A. GENERAL OPERATING SAFETY PRECAUTION A 1. 3. 4. Observe all the safety precautions in this manual when operating the tractor. Operate the tractor while wearing tight clothing that allows easy movement. Avoid loose jackets, mufflers, ties, scarves, or loose sh irt sleeves to prevent from being caught by moving parts. Always work when you are in good physical condition by taking sufficient rest to avoid overwork. Do n'ot allow children or adults having no knowledge of the tractor or tractor operation, to operate the tractor. Never allow riders on the tractor, linkage drawbar or attachments while travelling and operating them. A7. 8. B. Keep tractor steps clean to avoid accidents due to slippage. Cover the PTO shaft with a guard when not using. Be sure to apply the brake and lower any attachment or implement before disassembling any part. Never adjust or service the tractor when it is in motion or while the engine is running. Always adjust the brake or clutch properly in accordance with the adjusting procedure in the instruction book. Do not remove the radiator cap while the engine is running. Shut down the engine and wait until it cools sufficiently. For removal, turn the cap to the first stop to relieve pressure. To replace the coolant, use the coolant recovery tank. BASIC SAFETY TENANCE REQUIREMENTS FOR MAIN- Always follow these maintenance instructions before operating the tractor: 1. Immediately repair the head lights and work lamps required to conform to traffic regulations where the tractor is operated. -1- Hydraulic oil or fuel escaping under pressure can penetrate the skin, causing serious injury. Before disconnecting oil or fuel lines, be sure to relieve all pressure. Before restoring pressure after repair, be sure all connections are tight and all hydraulic components are in normal condition. If injured by leaked fluid, see a doctor immediately for proper treatment. When refueling, be particulary careful first to stop the engine completely to prevent the fuel from igniting. Never refuel in the presence of an open flame or while smoking. Always use funnel when adding fuel and refuel only out of doors. When refueling is completed, wipe any spilled fuel off the tractor and securely fasten the cap of the fuel tank. A 9. Before starting any work on electrical equipment or work that may cause you to touch the electrical part accidentally, first disconnect the battery cables. Never remove the ru bber cap cover at the positive terminal of the battery cable end. Before connecting the battery to the charger, make sure that the charger switch is in "OF'F" position. Be sure to connect the charger to the correct term inals on the battery, (positive to positive, negative to negative). A great amount of hydrogen gas is generated by the battery when it is being charged. Take precautions against fire: do not have any exposed flame in the area where you are working. Be sure not to cause any leakage of the electrolyte, since it will corrode the skin or clothing. In case of accident as described below, immediately seek first aid, and see a doctor immediately for proper treatment. a) If the diluted sulphuric acid from the battery has gotten into the eyes: Cleanse the eyes with a lot of clean running water for more than 15 minutes, while opening the eyes widely. b) If diluted sulphuric acid from the battery has been swallowed: Rinse the mouth with clean water immediately and drink a lot of raw eggs or milk. Lie down quietly. c) If diluted sulphuric acid has gotten on the skin or clothing: Wash away the diluted sulphuric acid completely with a lot of clean running water and neutralize with soap solution. Then rinse with water. d) If the diluted sulphuric acid is spilled: Wash away with a lot of water or neutralize with slacked Iime or bicarbonate of soda. C. 10. Stop the engine and make sure the PTO shift lever is in Neutral before performing any of the following services, including: a) Removal of the propeller shaft between PTO and any attachment, b) Adjustment of PTO drive train and hitch. c) Adjustment or cleaning of PTO driven attachment. 11. The steering wheel always has built-in play to some extent, which is required for smooth meshing of sector gear and pinion gear. Always inspect the amount of the play. Do not operate the tractor if there is too much or too little play in the steering. OPERATION OF THE TRACTOR Before driving the tracotr, follow these rules: C-1 Before Starting and Driving the Tractor Operate the tractor only when seated properly in operator's seat and keep a firm grip on the steering wheel at all times. Never attempt to perform any operation of the tractor from anywhere else, on or off th e tracto r. Always wear a "hard hat" when operating the tractor. A C-2 Starting and Driving the Tractor Always operate the tractor at the proper speed which enables you to keep the tractor under your complete control. -2 -- A Never attempt to jump on or off a moving tractor. A When starting the tractor, operating any attachment or engaging the PTO make sure that no one is in the way, especially children. I To start travelling, lower the engine speed and release the clutch pedal slowly. Abrupt releasing causes the tractor to jump off. Before leaving the tractor, stop the engine, remove the key, apply the parking brake and make sure that the engine has come to a complete stop, and any attachment is completely touching the ground. AWhen starting the engine in an enclosed area or building, ensure proper ventilation by opening the doors and/or windows to prevent carbon monoxide inhalation. Mount the extension exhaust pipe on the tractor which has a cabin. -r,,)j/ A Slow down when operating the tractor on rough round. f,") ) -3- A If the tractor is equipped with ROPS fasten the seat belt before using the tractor and keep it fastened while in operation. A Never operate the differentiallock speed or travelling on the road. For drilling the 4-WD tractor on the road, be sure to place the 4-WD shift lever in OFF position. C4 Steering and Turning the Tractor Slow down your tractor and disengage the differential lock before going into a turn, being careful to prevent any attachment mounted on the front or rear from hitting anyone or anything. A C-5 Towing and Operating on Hills For towing work on downward slope, place the shift lever in low speed and use engine brake. Never try to reduce the speed with brake only. Towing a heavy object on a hill is highly hazardous. Widen the tread of the tractor and mount the wheel weight or chassis weight to increase the stability and operate with extra caution. A A A Use of the seat belt is not recommended for ·tractor without ROPS. A When operating the tractor on eigher a steep slope or A C-3 Travelling on Roads and Streets For travelling on roads and streets be sure to lock both brake pedals together before driving to prevent either brake from acting independently. A flat ground, be sure not to suddenly steer, brake or operate clutch or attachments. Do not operate the tractor at the edge of cliff or steep slope. Be particularly careful right after the rain when soil is soft and may give way easily. / l -4- For towing, be su re to use the drawbar only. Set the hitch point below the center line of the rear axle. When using a chain, never try to move forward abruptly. When using a long chain or cable to hitch the tractor to the load, drive-the tractor forward slowly until all slack is taken out. C-6 Using Attachment To mount or operate attachments, follow the instruction manual for the particular attachment for safe operation. A When using agricultural chemicals with an attachment Avoid operating the tractor on an extreme slope that appears hazardous, when forced to operate on such slope, use extra care. Driving forward out of a ditch or mired condition or up a steep slope could cause tractor to tip over rear· ward. Back out of such situation if possible. If the situation does not permit you to back out, use the front wheel weight or the chassis weight for balancing the tractor lengthwise. Also in case any extra-heavy rear mounting attachment is used, try to obtain better balance in this manner. When backing down a slope in reverse gear or going up the grade in forward gear, never operate the clutch, brake, th rottle lever or steering wheel abruptly. Be particularly careful on slippery roads. In any case of towing (by use of a rope or by hanging up the front), be sure to place the both main shift lever and sub shift lever at "NEUTRAL" position 50 long as the rear wheels are on the ground. * These shift levers shall not be placed at any other speed range. When starting the engine by towing the tractor with a battery as discharged, be sure to place the main shift lever at the 3rd speed step and the sub shift lever at the high speed step, then operate the clutch slowly. /). * Never place the sub shift lever at the low speed step. ~ When towing the tractor, be sure to keep the safety speed. It is advisable to operate at 10 km/h (6.3 mph) or less in towing the tractor under 20 HP and at 20 km/h (12.4 mph) or less in towing the tractor over 20 HP. When towing or running on a steep downward slope, be sure to apply the engine brake to keep safety speed. Never run by inertia (coasting) with main shift lever placed "NEUTRAL" position or the clutch disengaged. on the tractor, always follow the instructions in the manual for the attachment as well as the instructions provided by the chemical manufacturer. C-7 Roll Over Portective Structure (ROPS) Strongly recommends a ROPS (RollOver Protective Structure) install to your tractor. A ROPS frame is available for these tractor. Tractors can be rolled over. Always tighten the bolts for ROPS mounting securely. Exercise good care in seat belt installation as regard belt strength and the bucket, which must not be broken off or disconnected. For further details, ask your delaer.

If not, ask the dealer for check. -10 - When the throttle lever is pushed forward, the engine speed reaches the maximum. The speed range controlled by the lever is 900 to 2,900 rpm (with no load). When the P.T.O. gear is shifted to "1 st" at 2,700 rpm (rated engine rpm), the P.T.O. shaft rotates at 623 rpm . CLUTCH When disengaging clutch you are advised also to lower the engine speed. The life of the clutch depends on the operating habit of the user. The clutch works in combination with PARKING BRAKE the P.T.O. ACAUTION Lowering the speed, when the tractor is overloaded, by half engaging the clutch or changing gear at high speed will damage the clutch lining. Disengaging must be performed completely in one clean quick movement with the engine revolution lowered as much as possible. 1 NOTE When the tractor is not used, the clutch should be disengaged by depressing the clutch pedal and the clutch lever should be hooked so that clutch linings will not get stuck. BRAKE The main brake is used for parking the tractor. Connect the right and left brake pedals with the locking plate, depress the brake pedal fully and lock with the stopper lever provided beside right side of transmission case. To release the parking brake, depress the brake pedal strongly and the parking brake is released automatically. FOOT SPEED CONTROL PEDAL The foot speed control pedal is installed on the right side of the step. When the hand throttle lever is in the idling position, the engine speed can be controlled freely within the range by depressing the pedal. The brake is of internal expansion type and is dirt and water proof. There are two pedals provided on the right side of the transmission case which are linked together by a plate. The brake is operated by depressing these pedals. To stop the tractor, lower the engine revolution, depress the clutch pedal and then depress the brake pedal. For turning in a confined space the right and left axles can be braked independently by removing the plate linking the right and left brake pedals. When travelling at high speed or on roads make sure that the right and left brake pedals are linked by means of the locking plate. When starting to travel on roads after one of the brakes has been operated more often than the other, check the balance of the right and left brakes beforehand. It is necessary to check brake balance once a week. If you fail to check the brake balance or to Iink the right and left brake pedals, there is every Iikel ihood that an accident will occur. AWARNING While travelling on roads, be sure to link the both right and left brake pedals. - 11 - NOTE When the hand speed control lever is in a high rev. position, the foot speed control pedal also moves into the position for those rev. When this is done the revolution cannot be controlled by means of the foot pedal within the range below the rev. set by hand lever. POWER TAKE OFF £ By operating the PTO shift lever located on left hand side of the transmission case, the three PTO speeds can be selected. DIFFERENTIAL LOCK When shifting the PTO shift lever, lower the engine speed depress the clutch pedal fully to interrupt the power from the engine and make sure the machine is brought to a complete halt.

This device links the right and left wheels in the transmission and rotates them at the same speed to prevent either wheel from slipping or to increase traction force. Engaging the Differential Lock Correct Incorrect A CAUTION 1. 2. 3. 4. 5. 6. 7. 8. When using a rotary tiller in the field with many stones or stumps or hard soil, where a lot of shock will affect on, care should be taken so that the rotary tiller will not be damaged. When using implements driven by PTO shaft, be sure to refer to implement manuals and operate them exactly as instructed. When any implement is towed by the tractor, care should be taken so that the universal joint does not form an angle of more than 15°. When the tractor is working with an impact load, correctly adjust the slip clutch on the implement side or use the shear pin of proper material so that the PTO is not overloaded. To reduce the thrust load to the PTO driven shaft as much as possible, it is advisable to run a test operation with an implement without any load. Lubricate the PTO driven shaft well. Avoid using a square-shaped drive shaft where practicable. Special care shou Id be given to the yoke position so that the driven shaft is well balanced. Before the tractor slips and the speed is lowered, depress the pedal with you r right foot and engage the differential lock. If the differential lock does not engage at the first attempt, repeat the operation more forcibly. If it still does not engage, lower the engine speed and after disengaging the running clutch, repeat the whole operation as described above. If either of the left or right wheel has already begun slipping, turn the throttle lever to the idle running or disengage the clutch, then depress the differential lock pedal. Make sure that the pedal is fully depressed. The farther the pedal is depressed, the better the lock is in effect. NOTE Removing your foot off the pedal automatically releases it, however if it is hard to release, depress either side of brake pedal instantaneously. How to Release the Differential Lock Immed iately after the right foot is moved off the pedal, the differential lock is automatically released by force of the spring. However, it must be remembered that the lock may not be released under special conditions. In th is case, the right and left brake pedals should be quickly and alternatively depressed, then, the differential lock will be set free. If the same occurs while plowing, the brake pedal of the land wheel side should be applied. The lock will be let out. When the both right and left brakes are Iinked for towing a trailer, operation of the steering handle to right and left allows the lock to be free. When the tractor is stopped with the differential lock applied, reverse running with a jerk can release the lock. ACAUTION Avoid using the differential lock when operating the tractor at high speed or running on a road. -12 - - " 8-SPEED TRANSMISSION 4-WHEEL DRIVE SHIFT LEVER The gear shift positions are as shown in the diagram below. By combination of the Main and High-Low shift levers, six forward speeds and two reverse speeds can be obtained. The first, second, and third forward speeds and first reverse speed can be obtained with High-Low shift lever in the LOW position, and the fou rth, fifth, and sixth forward speeds and second reverse speed can be obtained with the High-Low shift lever in the HIGH position.

The manual has been prepared for achieving tractor's maximum performance and safety for your work with this tractor employed. 1. Check the fuel level in fuel tank and replenish as necessary. 2. Check the levels of engine oil, transmission oil, and front drive differential. 3. Check the lubrication at every specified point on the chassis. 4. Check each bolt and nut for tightness. 5. Check the coolant level in radiator. 6. Check the fan belt tension for water pump, alternatorgenerator and cooling fan. 7. 8. 2. 3. NOTE In case fuel runs out, be sure to bleed the fuel system after retilling the fuel tank, otherwise the engine may not be started (or even stops soon after started). Check the air pressure in tires. Check every indicator lamp on instrument panel for operation. STARTING THE ENGINE 4. 5. 6. 7. 8. Open the shut off cock for fuel. Keep the parking brake applied. Place the main shift lever, High-Low shift lever and PTO shift lever in NEUTRAL. Set the throttle lever midway between its idling and high speed positions. Turn the starter key to "ON" position, push the check button to insure all warning lamps are on. And then release the button and see that oil pressure warning as well as battery charge warning lamps go on. Depress clutch pedal all the way and tu rn the starter switch to "START" position to start the engine. (If it is difficult to start, turn the starter key to "HEAT" position and wait for about 5 seconds before restarting.) Immediately after starting, release the starter key. The key will return to "ON" position automatically. Check the oil pressure and battery charge warning Iamps to see they went off. If not, stop the engi ne immediately and inspect. Perform warm-up run at about 1,500 rpm for about 5 minutes. ACAUTION 1. Use of the starter should be limited for about 10 seconds per trial. If it is not successful, wait for about 10 seconds before another trial. Using the starter intermittently without waiting for certain period of time, can cause the battery to run down. 2. Do not turn the starter while engine is running. It can lead to the starter failure. 3. Be su re to perform the warm-u p ru n regard Iess of the climate. Travelling before engine gets warm, shortens the engine life. -14 - In the temperature below freezing point, it may be necessary to use a engine block heater. ACAUTION After the engine has started comfirm that the engine is running smoothly listening carefully to ascertain if nothing abnormal sounds, and inspect for oil and water leakage. A 1. 2. 3. The fuel injection pump of this engine adopts the mechanism to ensure easier engine start by sufficient injection of fuel when the throttle lever is fully pushed. To start the engine specially in cold weather fully push the throttle lever, heat the glow plug enough and crank the engine. WARNING Do not use starting aids such as Gasoline or Ether in the air intake. Explosion may result. ENGINE BLOCK HEATER For easier engine start in cold weather, an engine heater may be used to heat engine coolant. Contact your nearest dealer for installation. AFTER THE ENGINE IS STARTED 1. Be sure to check the oil pressure and battery charge warning lamps to see they have gone off. If the lamp does not go off, immediately pull the throttle lever all the way backward and tu rn the starter key counterclockwise to shut down the engine, and locate the cause to correct. A CAUTION 2. Particularly, by starting the engine while oil pressure is too low, serious trouble could occur because of insufficient lu brication. Rotate steering wheel to see that front wheels turn to desired direction. DRIVING THE TRACTOR 1. 2. With the engine running, hold the tractor with the brakes if necessary. By pulling hydraulic control lever backward, raise the implement. A WARNING Raise or lower the implement with sufficient caution against any obstacle around. 3. Bring the engine speed to about 1,500 rpm (warm-up run). Depress clutch pedal all the way. Move each shift lever to desired position. 4. 5. 6. While travelling, interlock left and right brake pedals with locking plate so that they are appl ied simultaneously. A WARNING For travelling at high speed, interlocking the left and right brakes is particularly essential. Be sure not to travel at high speed with left and right brakes being independent to each other (not being interlocked). 7. 8. 9. Do not attempt to stop tractor using brakes, which may cause failure of transmission internals or prematured wear of brake linings. To avoid damaging brake or transmission system, be sure to release the parking brake before travelling. While increasing the engine speed gradually, release the clutch pedal slowly. A WARNING 1. 2. 3. 4. 5. 6. A Release the clutch gradually. Releasing it suddenly is hazardous causing the tractor to lunge. Before travelling backward, be sure to check for any obstacle beh ind the tractor. For travelling on public road or working at high speed, be sure to lock the left and right brake pedals with locking plate so that both brakes are applied simultaneously. During high speed operation or travelling on road, do not use differential lock. The 4-wheel drive shift lever and PTO shift lever should be placed in "OFF" and "NEUTRAL" positions respectively. While travelling, remove your foot off the clutch or brake pedals. Independent use of left or right brakes should only .be allowed for low speed operation. 8. 9. Apply parking brake. Push hydraulic control lever slowly forward to lower implement to ground. 10. Remove the key. 11. Close fuel shut off valve above fuel filter. A CAUTION 1.

To tow an attachment or trailer, be sure to use the drawbar. 3·POINT LINKAGE It is adjustable spring supported seat in 3 stages at increment of 30 mm (1.18 in.) to suit to the operator's stature. TOOL BOX This tractor is provided with a 3-point linkage of category 1 . The implement which is to be mounted, must match the 3-point linkage. NOTE When an implement is towed with the linkage drawbar installed on lower links, the lower links should always be kept horizontal. HYDRAULIC SYSTEM Your tractor is provided with the live hydraulic system in which a hydraulic pump is driven directly by the engine camshaft and always makes the oil circulate to exert the hydraulic pressure while the engine is running. The tool box is located under the operator's seat. To use the tool box, turn the seat downward to the front. The hydraulic oil of exclusive use is reserved in the transmission case and passed through the oil filter, thus ensuring effective operation. DRAWBAR Position control, flow control (down speed control) and lock of the implement are possible with the hydraulic control lever installed on the right side of the seat. For external service, the hydraulic pressure can be taken out by fitting an adapter plate to the delivery pipe installed on the left side of the seat. - 17- FLOW CONTROL KNOB POSITION CONTROL Position control is provided for determining and holding the position of an implement as desired by means of a lever. Normally it is utilized for the work employing rotary tiller, broadcaster, mower or rake. To use the position control, operate the control lever in the following manner: • Pulling the lever backward will cause an implement to rise. • Pushing forward will cause an implement to lower by its own weight. • Placing the lever at certain position, causes implement to move to and stop at the height corresponding to the position of the lever. • For holding the height of the implement at certain position constantly, use stopper A to fix the lever position, which will make the lowered position of an implement to be maintained at the constant height. A CAUTION Stopper B is provided to prevent the hydraulic safety valve from being actuated. Be sure not to move it for any purpose other than hydraulic power take off. For returning the displaced stopper B to its original position, first operate the position control lever in upward direction, then from the position where actuating sound of the safety valve starts, slide the stopper B downward by 5 to 8 mm and tighten it there. -18 - MT160/D and MT180/D provide the flow control knob which controls the lowering speed of the implement. It is located in front of the hydraulic case under the seat. When the knob is turned clockwise, the lowering speed slows down, and when further turned, the control valve is closed. As a result, the implement will be held in its position and will not move downward any further. Turning the knob counterclockwise increases the lowering speed. NOTE Adjust the lowering speed according to the type of an implement and operating condition. Rotary tiller operation . . . . . . Lowering speed - Slow Plow operation . . . . . . . . . . . Lowering speed - Fast AWARNING 1. For travelling on the road, be sure to turn the flow control knob all the way clockwise and lock it there. 2. During tine replacement, or grass or straw removal of rotary tiller, or during inspection of implement, for the safety, place the position control lever in upward position, shut down the engine and be sure to lock the flow control lever. EXTERNAL HYDRAULIC SERVICE Lift arm The hydraulic pressure can be used to control the implement installed to the tractor. NOTE When taking out the hydraulic pressure, be watchful of oil level in the transmission case and sticking of the pump to be caused by oil shortage. PTI/4 iI I J HydrauliC l:=~~ntrol valve .. ~~_,.

HOOD AND SIDE COVERS OPENING/CLOSING Before opening the hood for pre-start inspection or light servicing, push a knob at the hood rear in the direction of the arrow marked on knob. CHECKING THE RADIATOR COOLANT LEVEL • Remove the radiator cap to see if the coolant is upto the filler port. • A CAUTION 1. Use clean soft water only. 2. River water, etc. may cause rust, corrosion or clogging in the radiator or engine. 3. See paragraph "ANTIFREEZE" for its use. Loosen the coolant cock at lower right of the engine and drain the coolant. For replenishment, remove the radiator cap and enter water upto the radiator filler port. AWARNING Be sure to loosen the coolant cock only whi Ie the engine is cool. PRECAUTIONS WEATHER Radiator cap ON COOLING SYSTEM IN COLD Frozen cooling water may damage the cylinder block. To avoid such a trouble, mix antifreeze into cooling water, or thoroughly drain cooling water from the cylinder block in case the tractor is stored or left unused for a long time in cold weather. AWARNING Do not remove the radiator cap except for checking the coolant level or coolant replacement. Removing the cap immediately after operation is hazardous because pressurized hot water will jet out. Stop the engine and wait until it cools down before removing the cap. ANTIFREEZE When adding antifreeze solution, the following rules should be observed, otherwise, the cylinder block will rust. 1. This tractor's engine is of a diesel type and its cylinder block is made of cast iron. Therefore, suitable a{ltifreeze solution for such a cast engine block must be used. 2. Before adding mixture of antifreeze and water, completely drain cool ing water and clean the radiator with detergent. 3. Water to be added to antifreeze should be clean soft water. 4. When antifreeze is no longer used, drain and wash the cooling system using detergent and fill it again with clean water. Do not re-use antifreeze drained from the engine. -26 - .. 5. 6. 7. 8. 9. Treat antifreeze carefully so that it may not remove paint from the cylinder block. Any antifreeze solution (antifreeze and water), even if it is permanent antifr~ze, snQuld ffet be used for more than 2 years. Confirm that there are no leak from the hose connections or cylinder head gasket. Antifreeze with proper density to suit the climate in your area should be used. When antifreeze is used over a long period in winter, measure the specific gravity frequently. NOTE Consult your dealer concerning detergent and antifreeze.

Step on both brake pedals simu Itaneously and check the trace of tire slippage for uneven braking. If the tractor stops straight, braking is normal. If it stops with turning, readjustment is required. -37 h Loosen the lock nut on the differential lock pedal stopper, and screw in the stopper bolt. With pedal depressed, adjust the stopper bolt so that it lightly contacts the pedal. Then, screw out the stopper bolt by a quarter to half turn and lock the stopper bolt. THROTTLE LEVER ADJUSTMENT The engine speed can be controlled by operating the throttle lever on the right side of the instrument panel. The range of speed control is as follows: Low idle speed. . . . . . . .. 900 rpm High idle speed ......... 2,900 rpm 1. Place the throttle lever in the low idle speed position, and loosen the nut securing the speed control rod to the joint. While watching the tractor meter on the instrument panel, turn the nut so that the engine idles at 900 rpm, and lock the nut. 2. Pushing the throttle lever fully forward makes the engine to run at the maximum of 2,900 rpm. Pulling the throttle lever fully rearward causes the engine to run at the low idle speed. 3. NOTE 1. The high speed adjusting bolt is pre-adjusted and sealed, before leaving the factory, so that the engine ru ns at the specified maximum speed with the throttle lever pushed fully forward. If such specified speed is not obtained, consult Mitsubishi dealer. 2. Adjust the throttle lever properly with the nut at the throttle lever supporting point so that it may not be moved by the vibration of the engine nor by the tensed governor spring and besides, may control the engine speed .smoothly enough. • HYDRAULIC CONTROL ADJUSTMENT The hydraulic control link has been carefully adjusted in the factory, so that adjustment is hardly ever necessary. However, if it is not working correctly, adjust it in the following manner: When carrying out this adjustment, stop and start the engi ne as requ ired. A The hydraulic system is equipped with a pump relief valve to protect the hydraulic pump and pipe line against accidents caused by high hydraulic pressure in the system. The set pressure is 135 kg/cm 2 (1,920 psi) at full flow. Never disturb nor disassemble the pump relief valve since its adjustment requires special tools and instruments. Joint Feedback I ink b~ 5 ~ 15mm (0.2 ~ CAUTION Be sure to check that there is no relief sound (beeps) generated after adjustment.

Lift arm Generator Ram shaft Nut~ Joint Arm Start the engine, and operate the hydraulic control lever to raise the lift arm to the maximum lifting position without implement. With the arm so raised, stop ,the engine, and check to be sure that there is a play of 5 to 15 mm (0.2 ~ 0.6 in.) at the top of the lift arm by hand. CD fI ED Move stop lever on lifting end all the way and fix it there. Have a lift rod for implement removed off the lift arm. With engine running at about 1,000 rpm, raise the control lever until it contacts the stopper and check the amount of play at lift arm end to be about 5 ~ 15 mm (0.2 ~ 0.6 in) with the lift arm lifted. NOTE • • • Without this play, hydraulic circuit will be subjected to unnecessary pressure when implement is lifted, causing trouble. If play is too small or not available, loosen feed back link nut and turn the feed back link to the direction of lift arm for adjustment (tightening direction). If play is too great, adjust it in direction away from lift arm (loosening direction). Be sure to lock the feed back link nut after adjustment without fail. -38 - The generator is of an alternator type. Seal bearings are employed for this generator, so that lubrication is not necessary. During maintenance, pay attention to the following points. 1. The generator is negative-grounded and if the polarity is reversed, the diode will be damaged. Be careful enough when connecting it to the battery. 2. As the battery voltage is always connected to the terminal A, never run the engine with the terminal A disconnected. 3. Don't water the alternator at high pressure. 4. Pay full attention to the belt tension so that normal charging may be made. 5. During operation, be sure to set the starter switch at "ON". 6. If difficulties are experienced, consult Mitsubishi dealer.

Never use a fuse of a large capacity. instruments are necessary for servici ng the When the rotational force of the motor is the battery voltage because it may be caused battery capacity. When the voltage is correct and there is still inferior rotation, let your dealer check the carbon brush for deterioration and magnetic switch for defective performance. The motor sometimes does not start even when the light is sufficiently bright. The cause may be due to trouble in the regulator or a loose battery terminal connection. When the starter motor does not operate, don't continue to drive it because it will result in damage to the motor or battery. In this case, consult your dealer. Y G R (bold) REGULATOR The regulator is an important part for the electrical system protection of your tractor. When trouble occurs with the regulator, consult your dealer because specific knowledge and special instruments are required to repair it. GLOW PLUG The glow plugs are of a sheathed type and connected in parallel. Therefore, if one of the plugs is disconnected, performance is not totally defective. When the heat wire of the glow plug is disconnected, the preheat time of the control resistance is abnormally prolonged. When the center polarity, the body and the sheath come is contact with one another, the glow signal lamp will be heated quickly and the wiring of the pre-heated circuit will burn out. -39 - Y CD G @ R/L R/W @ ~I Combination flash and turn signal lights 2 Horn and work light 3 Instrument lights 4 Headlights and red tail light Fuse box REOPERATION AFTER STORAGE SECTION 7. STORING 1. STORAGE A tractor should be stored in a dry and protected place when it is left without use for some period. It should be noted that leaving a tractor outdoors will result in shortened Iife of the tractor. For storing the tractor please follow the procedures shown below: 1. After washing and cleaning the tractor be sure to lubricate it. And if hydraulic implement is mounted apply rustinhibiting grease to all the exposed cylinder or piston rod su rfaces. 2. Run the engine until oil in the crankcase gets warm enough, then drain oil and replace oil filter. Refill the crankcase with fresh oil specified in the "LUBRICATION TABLE" and run the engine for five minutes or so. 3. 2. 3. 4. 5. 6. 7. Store the tractor in the place where the tires may not be in the sun. Before storing wash and clean the tires. In case of long term storage jack up the tractor so that the tires may be under no load. When the tractor is not jacked up inflate the tires periodically_ After the engine gets cooled enough, pour one tablespoonful of engine oil from the air breather pipe. To distribute the oil allover the cylinder walls, crank the engine for five or ten seconds. Be sure to reinstall the breather hose on the pipe after pouring oil. 5. Drain the engine cooling system and fill it with a mixture of antifreeze and water as specified on the container for the lowest expected temperature. 6. Fill the fuel tank with fuel, and clean the fuel filter. 7. Plug up the end of the exhaust pipe. 8. Clean the air cleaner and then cover it so as to seal the air intake system. 9. Check the battery for proper electrolyte level and specific gravity at least once a month. In order to increase the durability as well as prevent freezing, the battery should be kept fully charged all the time. 10. Hold the clutch at the disengaged position in use of clutch lock, so that clutch facing will be prevented from sticking to the flywheel or clutch pressure plate. Check to make sure that viscosity of the oil in the engine crankcase is as specified in "LUBRICATION TABLE". Remove the plug from the exhaust pipe. Remove the cover over the air cleaner. Check to make sure that the battery is fully charged and the terminal is clamped tightly enough. Fill the fuel tank. Release the clutch pedal.
